Apparatus for point of service manufacture of custom cranial remodeling devices

ABSTRACT

Apparatus provides point of service to manufacture a custom cranial remodeling device for correction of cranial deformity of a subject. The apparatus comprises capture apparatus disposed at a physical location for capturing three dimensional digital data of the head of the subject and generating a three-dimensional digital data file representative of the head and an additive manufacture device located at the physical location. The apparatus further comprises a processor that operates to process the three-dimensional digital data file to produce a device file comprising the shape for the custom cranial remodeling device. The processor provides the device file to the additive manufacture device. The said additive manufacture device operates to utilize the device file to manufacture the custom cranial remodeling device at the physical location.

The present invention pertains to custom cranial remodeling devices custom manufactured for subject patients and methods of manufacturing such devices.

The applicant of the present invention has pioneered the treatment of plagiocephaly in infants through the use of cranial remodeling devices that are each custom manufactured for each infant patient and has pioneered the customized manufacture of such devices.

One method of manufacturing custom cranial remodeling devices comprises capturing a three-dimensional digital image of the entirety of a patient's head to produce a digital file of the entire head, processing the digital file to generate a second digital file that represents a three-dimensional digital image of the entirety of a desired head shape for the patient, fabricating a life size model of the desired head shape, vacuum thermo-forming a foam liner onto the life size model, vacuum thermo-forming a hard plastic onto the foam liner, generating trim lines for the device, projecting the trim lines onto the hard plastic, cutting the trim lines, and manually finishing the trimmed cranial remodeling device.

Each different step in a manufacturing process presents the possibility of introduction of error or inaccuracy. Accordingly, it is desirable to reduce the number of steps to manufacture custom cranial remodeling devices.

In addition, a clinician typically captures the three-dimensional digital image of the entirety of a patient's head at a clinic and the manufacturing steps occur at one or more other physical locations. Because of the physical separation of the clinic and the manufacturing locations, the custom cranial remodeling device must be shipped from the manufacturing facility to the clinic resulting in a time delay that is measured in days.

Accordingly, it is also desirable to provide point of service manufacturing of cranial remodeling devices such that the manufacture occurs at the clinic location.

Optimally it is desirable to change out cranial remodeling devices frequently. By adding a foam liner, the cranial remodeling devices could be adjusted by a clinician to accommodate for the patient's growth. The foam liner is provided to extend the life of the product.

In addition, the inside foam liner does not always compress evenly under vacuum. When released from vacuum, there is some spring back of the material. The result of the spring back may result in the foam layer not retaining conformance to the model.

Accordingly, it is also desirable to manufacture cranial remodeling devices that are so accurately manufactured and easily manufactured such that it is not necessary to include a foam layer.

For example, digital capture apparatus 103 may use a laser or other beam emitting scanner of a type described in U.S. Pat. Nos. 6,572,572 and 6,340,353, both of which are assigned to the assignee of this invention. Digital capture apparatus 103 may alternatively comprise optical capture apparatus such as that described in U.S. Pat. Nos. 7,142,701, 7,162,075, 7,245,743, 7,280,682, 7,305,369, 7,542,950, 8,103,088, and 8,217,993 all of which are also assigned to the assignee of this invention. The disclosures of all the above-listed patents are incorporated herein by reference.

Image capture apparatus 103 processes the captured data and generates a captured head data file 105 for the subject's head. In addition, image capture apparatus 103 processes data file 105 to generate a modified head data file 107. The head shape represented by modified head data file 107 represents a desired or corrected head shape for the subject. The methodology for generating the modified head shape data file is described in the above-identified patents and additionally in U.S. Pat. Nos. 8,442,288, 8,442,308, 8,472,686, 8,494,237, and 8,787,657 all of which are assigned to the assignee of this invention. The disclosures of these additional patents are incorporated herein by reference.

The captured head data file 105 and modified head data file are both accessed by processor 109 executing program 111 to generate a device data file 113 that completely defines a custom cranial remodeling device for subject 101. The operation of processor 109 executing program 111 is described in detail herein below.

Device data file 113 is provided to an additive manufacture device 115. Additive manufacture device 115 utilizes device data file 113 to manufacture a custom cranial remodeling device 117 for subject 101.

Additive manufacture device 115, in one embodiment is a commercially available three-dimensional printer that is operable to deposit layers of material to form cranial remodeling device 117. It will be recognized by those skilled in the art that there are various types of additive manufacture devices that are commercially available and the present invention encompasses those various types of additive manufacture devices.

The embodiment shown in FIG. 1 provides digital capture apparatus 103 and additive manufacture device 115 at the same physical location. In addition, processor 109 may also be located at the same physical location or located remotely from the clinic 100 and data linked thereto to provide the effect of being located at clinic 100.

It will be further appreciated by those skilled in the art that although a separate processor 109 is shown in FIG. 1, processor 109 is merely representative and may comprise one or more processors that are either located at clinic 100 or at a remote location or some combination thereof. Still further processor 109 may be incorporated into digital capture unit 103 such that the processor of digital capture unit also executes program 111 to generate device file 113.

Digital capture apparatus 103 operates on captured subject head data representing the digital image of the head of subject 101 to mathematically remove the subject's body and other extraneous information to establish a subject data file. The digital image of the subject's body is mathematically cropped or removed leaving just digital data representative of the digital image of the subject's head to provide three-dimensional cropped subject data.

The three-dimensional cropped subject data is oriented into a predetermined standardized orientation for further processing to produce a cropped and oriented data file that is referred to as the captured head data file 105.

It will be appreciated by those skilled in the art that in other embodiments, program 111 may provide the cropping and orientation functions that are provided by digital capture apparatus 103.

Processor 109, executing program 111, utilizes captured head data file 105 to generate curvature maps of the subject's head. A plurality of different types of curvature maps are generated by processor 109, executing program 111. Specific ones of the curvature maps are used to locate specific curvatures and features for a cranial remodeling device. Program 111 is utilized to create, reference, and cross-reference the curvature maps to determine an optimal position of a device contour.

The term “contour” as used herein is the shape that defines the what in the past has been called “trim lines” for cranial remodeling devices that were formed by first thermoforming foam and plastic layers onto a head model and then cutting or trimming the foam and plastic to a final shape of the cranial remodeling device to be worn on the head of a subject.

The program identifies anthropometric landmarks to determine the contour of the device.

In the embodiment describe below, the cranial remodeling device comprises bottom and top contour lines 117 a, 117 b. The bottom contour line 117 a and the top contour line 117 b are each calculated for cranial remodeling device 117 by processor 109 executing program 111 operating initially captured head data file 105.

Turning now to FIGS. 2 and 3 execution of program 111 to calculate bottom contour line 117 a is described first and then the execution of program 111 to calculate top contour line 117 b is described.

FIG. 2 illustrates a curvature map 201 of a frontal view head of subject 101. Program 111 is executable to determine a bottom anterior contour line segments or splines by first mathematically defining two exocanthion locations 203 a, 203 b, the two frontozygomatics points 205 a, 205 b on the head, and the glabella 207. Using these five points 203 a, 203 b, 205 a, 205 b, 207 as a spatial reference, an elliptical cylinder shape is used to create the orbit contour splines 209 a, 209 b.

Program 111 executed by processor 109 identifies the sagittal plane 215 and uses sagittal plane 215 to identify the location of a key portion 211 of cranial remodeling device 117. In the embodiment, program 111 as executed by processor 109 generates a contour for key portion 211. Key portion 211 dips a predetermined distance below an orbital horizontal that is identified by program 111.

Turning now to FIG. 3, program 111 as executed by processor 109 identifies a coronal plane 301 on the head and anterior temporal extension lines 303 a, 303 b are attached to the ends of the orbital splines 209 a, 209 b at the exocanthions 203 a, 203 b and continue down parallel to coronal plane 301.

Program 111, executed by processor 109 generates ear contours or splines 305 for each ear. The location of ear contours 305 are determined by mathematically defining the top ear points 307, bottom ear points 309, front ear points 311 and back of ear points 313 and connecting the points 307, 309, 311, 313 for each ear with a curved spline 315. In addition to determining the ear contours 305, the midway point of the total length of the ear is defined.

The location, size and shape of the temporal piece contours 315 are determined by using the mathematically defined exocanthion points 203 a, 203 b and front ear points 311. The location of the bottom 317 of the temporal contour 315 is a predetermined portion x of the ears total lengthy above the bottom ear point 309.

Program 111, executed by processor 109, calculates a neck inflection portion of the contour. The location of the neck inflection contour portion is determined by using a mathematically defined neck inflection and the ears bottom points 309. The final location of the neck inflection point 321 is determined by calculating a weighted average between the mathematically defined neck inflection point and the ear bottom points 309.

Program 111, executed by processor 109, calculates an angle of the neck inflection contour is determined by calculating a guideline that connects the neck inflection point 321 to a chin point 323.

Program 111, executed by processor 109, calculates mastoid contours 331. The location, size and shape of the mastoid contours 331 are determined by using the mathematically defined ear points 307, 309, 311, 313, the neck inflection point 321 and chin point 323. A guideline 325 that connects the neck inflection point 321 to the chin point 323 is calculated. A line 331 perpendicular to the guideline 325 is placed a predetermined distance from the posterior ear point 313.

Curved contour portions 333 are each calculated, sized and positioned to be tangent to the back of the ear spline 305 and contact both the neck inflection point 321 to guide line 325 and line 331. The shape of each curved contour portion 333 is different for each head.

In the embodiment, cranial remodeling device 117 further comprises a top contour 117 b.

Program 111, executed by processor 109, identifies a point 221 of low curvature on the sagittal midline 223 above the frontal bones as the location of an anterior superior contour.
